Creating a connection using certificates

Certificates can be considered as a seal of trust, which allows you to communicate with the Qlik Engine directly with full permission. As such, only backend solutions ever have access to certificates, and you should guard how you distribute them carefully. To connect using certificates, you first need to export them via the QMC, which is a relatively easy thing to do:

Once they are exported, you need to copy them to the folder where your project is located using the following code:

<html>
<body>
<h1>Mastering QS</h1>
</body>
<script>
var certPath =  path.join('C:', 'ProgramData', 'Qlik', 'Sense', 'Repository', 'Exported Certificates', '.Local Certificates');

var certificates = {
        cert: fs.readFileSync(path.resolve(certPath, 'client.pem')),
        key: fs.readFileSync(path.resolve(certPath, 'client_key.pem')),
        root: fs.readFileSync(path.resolve(certPath, 'root.pem'))
        };

// Open a WebSocket using the engine port (rather than going through the proxy)
var ws = new WebSocket('wss://server.domain.com:4747/app/', {
        ca: certificates.root,
        cert: certificates.cert,
        key: certificates.key,
        headers: {
                        'X-Qlik-User':  'UserDirectory=internal; UserId=sa_engine'
        }
        });
       
ws.onopen = function (event) {
 // Call your methods
}
</script>
